That is one of my axle builds, I used a F-250 hp44 as it uses 3" tubes instead of 2 3/4" tube. Used stock ford 60 inner c's and made a sleeve to make up the 1/8" of difference. The outters were so he could run 5 lug, otherwise you can run stock ford outers if you want 8 lug. The short side is a stock ford 60 shaft and the long side is a cut down stock ford unit.

Did you make the sleeve by taking a 1/8" piece of mild sheet and wrap the tube with it? How wide did you make the sleeve? Just to fit in the knuckles or did it cover a little more of the axle tube?

The reasons for the questions is I have access to some D60 knuckles and have a D44R housing. I want to know if the build is going to handle 37's. The D44R I run now is always a crap shoot. Some days it is unbreakable, other days it spits out joints and shafts.
